The refrigerant circulation system comprises a compressor 5, a condenser 6, a throttling element 7 and an evaporator 8 connected through a refrigerant pipeline 4. At the air inlet of the condensing centrifugal fan 2, a condensing air inlet cavity 9 communicating with the outside of the machine body 1 is formed through a partition board, and at the air outlet, a condensing air outlet cavity 10 communicating with the outside of the machine body 1 is formed through a partition board. The condenser 6 is arranged inside the condensing air inlet cavity 9. At the air inlet of the evaporating centrifugal fan 3, an evaporating air inlet cavity 11 communicating with the outside of the machine body 1 is formed through a partition board, and at the air outlet, an evaporating air outlet cavity 12 is formed through a partition board. The evaporator 8 is arranged inside the evaporating air inlet cavity 11. An air outlet channel one 13 and an air outlet channel two 14 are arranged on the evaporating air outlet cavity 12. The air outlet channel one 13 communicates the evaporating air outlet cavity 12 with the outside of the machine body 1, and its air outlet is arranged on the side of the machine body 1; the air outlet channel two 14 communicates the evaporating air outlet cavity 12 with the outside of the machine body 1, and its air outlet is arranged on the front side of the machine body 1; valves are respectively arranged on the air outlet channel one 13 and the air outlet channel two 14, and the air outlet of the condensing air outlet cavity 10 is arranged on the rear side of the machine body 1.

[0027] The working principle of the present utility model: As shown in Figures 1-4, the air inhaled by the condensing centrifugal fan 2 exchanges heat with the condenser 6 in the condensing air inlet cavity 9 and then flows out through the condensing air outlet cavity 10. The air inhaled by the evaporating centrifugal fan 3 exchanges heat with the evaporator 8 in the evaporating air inlet cavity 11 and then flows out through the evaporating air outlet cavity 12.

[0028] There are three application scenarios of the present utility model:

[0029] The first scenario: Place the present utility model indoors. The air inlet of the condensing air inlet cavity 9 and the air outlet of the condensing air outlet cavity 10 are respectively connected to the outside through pipelines. Close the valve of the air outlet channel one 13 and open the valve of the air outlet channel two 14. The condensing centrifugal fan 2 inhales outdoor air, exchanges heat with the condenser 6, and then flows back to the outside through the condensing air outlet cavity 10. The evaporating centrifugal fan 3 inhales indoor air, cools it through the evaporator 8 to form cold air, and then flows out to the indoor through the air outlet channel two 14, forming an indoor cycle.

[0030] The second scenario: Place the present utility model outdoors. The air outlet channel one 13 is connected to the indoor through a pipeline. Open the valve of the air outlet channel one 13 and close the valve of the air outlet channel two 14. The condensing centrifugal fan 2 inhales outdoor air, exchanges heat with the condenser 6, and then flows back to the outside through the condensing air outlet cavity 10. The evaporating centrifugal fan 3 inhales outdoor air, cools it through the evaporator 8 to form cold air, and then flows out to the indoor through the air outlet channel one 13, which is applicable to environments with large space and non-closed. Usually, the indoor air can flow out through the door gap to avoid excessive indoor pressure.

[0031] The third scenario: the utility model is placed outdoors, the valve of the air outlet channel 1 13 is closed, and the valve of the air outlet channel 2 14 is opened. The condensing centrifugal fan 2 inhales outdoor air and flows back to the outdoors from the condensing air outlet chamber 10 after heat exchange with the condenser 6. The evaporating centrifugal fan 3 inhales outdoor air and forms cold air after cooling by the evaporator 8, and flows out to the outdoors from the air outlet channel 2 14, that is, blowing cold air directly to the front side, which is suitable for cooling open outdoor local environments such as stadiums and concerts.

[0032] The utility model arranges the compressor 5, the condenser 6, the throttling element 7 and the evaporator 8 in the machine body 1. When disassembling and moving, there is no need to disassemble the refrigerant pipe 4, and there is no need to re-inject the refrigerant during installation. The utility model is easy to disassemble and move, and there is no waste of refrigerant. The utility model can cool down the indoor environment as well as the outdoor open local environment, and has a wide range of applications. At the same time, the utility model arranges two channels, an air outlet channel 13 and an air outlet channel 2 14, which are connected to the evaporation air outlet chamber 12, and valves are respectively arranged on the air outlet channel 13 and the air outlet channel 2 14, so that the utility model can be placed outdoors or indoors. When the utility model is placed outdoors, the indoor noise can be effectively reduced.

[0033] The utility model arranges the air outlet of the condensation air outlet chamber 10 at the rear side of the machine body 1, which effectively avoids the situation in which the hot air from the condensation air outlet chamber 10 directly affects the cold air from the second air outlet channel 14 when the third scenario is used.

[0034] Furthermore, the throttling element 7 is an expansion valve or a capillary tube. In this embodiment, the throttling element 7 is a capillary tube.

[0035] Furthermore, the valve is a butterfly valve, a gate valve or a multi-leaf regulating valve.
